ERIB, OF ROSELLE PARK, NEW JERSEY, ASSIGNOR TO AMERICAN CAN COM-- PATENT OFFICE IPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY COMPOUND LINING MACHINE Application filed August 15, 1927. Serial No. 212,885.

This invention relates in general to machines for applying a lining compound or gasket material to the flanges of flanged can ends to enable them to be interfolded with the flanges'of flanged can bodies to form the now usual hermetic solderless end seams of the tin can of commerce. The invention has more particular reference to the application of compound to the end by a printing die and through the employment of acompound of relatively thick or viscous character.

In the die lining of can ends from certain standpoints it is desirable that the die move up from beneath the surface of a body of compound in a tank and imprint upon the flange of the end the desired amount of compound upon the canend. The ends, to receive a compound from a die thus moving, must be arranged of course with the flange area to be lined facing downwardly, and while the material is of sufficient viscous character to cause it to adhere in desired amount to the end, it is desirable that the end be immediately thereafter inverted and final drying accomplished in the inverted position to the end that the material may spread to form the film required over the area provided for its reception.

An important object of the invention is in the provision of means for applying a lining compound to the flanges of can ends in downwardl opening position, and in inverting and cl elivering the lined can ends with the flanges opening upwardly for drying the compound and further operatlons upon the can ends in upright position.

A further object of the invention is the provision of means for receiving can ends in one position and for delivering them at a different elevation in an inverted position.

A further important ObJGCt of the invention is in the provision of improved means for preventing the application of lining C0111- pound when there is no can end in the com-' pound receiving position.

A further important object of the invent1on is in the provision of a horizontal carrier with a number of faces provided with magnetic. means for holding a can end in position on each of the faces.

A still further object of the invention is.

understood from the following description,

which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

ings, a machine support frame designated generally with the numeral 11 is mounted in ,a suitable supporting base 12, and carries can ends 15. t

The can ends 15 are stacked in a magazine comprising a base plate 16 supported by the frame 11 and rods 17 extending upwardly therefrom so the can ends can be fed at the top.

.The lower-most can end in the magazine is separated from the remaining can ends and moved horizontally by a reciprocating feed bar 18, as shown more clearly in Figures 5 and 6, which has a lower projection 19 to en gage below the edge of a can end 15 and an edged plate 20 with a rounded extremity 21 spaced above the extension 19 and adapted to engage the edge of the lowermost can end in the magazine.

The feed bar is is attached to a plate 22 slidable in guides 23 supported by the machine frame 11. The plate 22 is attached to a block 24 pivoted to one end of an adjustable link 25, the other end of which is pivoted to the upper end of an operating lever 26 (see Fig. 1), the lower end of which is pivoted in a bracket 27. This lever if oscillatedbv a link 28 pivoted at one end of the lever, and at the other to a crank disc29 at the end of an operating shaft 30. a

A cut-out lever 31 (Fig. 5) is operated by the reciprocation of feed bar 18, which is formed on one side with a cam surface 32. The lever 31 is pivoted intermediate its ends and carries a cam engaging roller 33 at one end, which is held against the cam surface 32 by a spring 34 attached at one end to'a projection 35 of the lever 31, and at the other end to the machine frame 11 by a screw 36. At the other end of the lever it carries a separator blade .37 adapted to pass between the lowermost can end in the magazine and the next one to it in timed relation, so that when the feed bar 18 is moved to discharge the lowermost can end from the magazine, the

roller 33 will ride up on the cam surface 32, moving the separator blade 37 inwardly to partially support the stack of can ends until the feed bar 18 is moved oppositely into position to again engage the lowermost can end. The can end carrier to which the can ends are fed comprises a rotatable drum 40 mounted for rotation on a horizontal shaft 41, as shown more clearly in Fig. 4, by means of a key 42 wedged in position by a .bolt 43, movable in a recess 44 in the end-of the shaft and secured in place by a nut 45 at the outer end of the bolt.

Each supporting face of the carrier drum 40 (Figs. 4 and 6) comprises a plate 46 and an attached disc 47, both secured to a projecting core piece 48 forming an annular face 49 corresponding to and for receiving the shape of a can end to be lined. In the drawings a circular face is shown, although a can end of any desired shape may be accommodated. Surrounding each core piece 48 below the face plates is a magnetic winding coil 50 for energizing the magnets thus formed and for attracting and holding can endsin position on the carrier.

v Current is supplied to the ma net coils 50 by collector rings 51 and 52 (see ig. 4) connected by conductors 53 and 54 respectively with the windings, the rings being engaged at another location by brushes (see Fig. 8)

55 and 56, which are in turn connected to 7 electrical supplyconductors 57 and 58.

Thecarrier drum shown is formed with six can end receiving faces, each of which is brought successively in position to receive a can end from the feeding bar 18, the can end being supported in its feeding movement by plates 59, which constitute an extension of the magazine or the machine frame 11. At

cle 63 of lining compound 64. The outer end.

61 ofthe arm 61 is secured by screws 62 to a slide 65 movable in vertical guides 66 formed in a frame part 67 projecting upwardly from the main frame 11. At the lower end of the slide 65 it is connected by a coupling 68 (see Figs. 4 and 8') with the upper threaded end of a shaft 69 held at one end of a sleeve 70 by a shoulder 71 on the shaft and a spring 72 within the sleeve bearing against the shoulder 71 and against a bushing 73 threaded in the lower end of the sleeve through which the shaft 69 also extends, said shaft having a squared portion 74 at its outer end and a nut 75 to engage the coupling 68 for adjustment.

To raise and lower the lining device, the sleeve 70 is provided with a crank pin 76 mounted in a crank disc 77 at the end of a shaft 78 ournalled in bearings 79 of the frame extension'67 and 80 of a gear housing 81.

;The continuous rotation of shaft 78 recipro- '70 and the shaft 69 is to stop the die without interfering with the rotation of shaft 78 when a can end is not in the lining position.

To control the operation .0 the lining die a stop bar 82 is mounted for transverse movementin the frame extension 67 (see Figs. 4,

5 and 8) in the path of movement of a block 83 secured to the back of the slide 65, the rod and, the block having corresponding recesses '84 and projections 85 respectively so located that when the rod is in one position the projections 85 will enter the recesses 84 permitting a full raising movement of the die 60, but when the rod 82 is in another position the projections 85 will not engage in the recesses 84 of the rod and the full lining applying movement of the die will be arrested, bringing into action the flexible connection between the. shaft 69 and sleeve 70. The oscillation of the rod .82 is effected by the mechanism shown more clearly in Fig. 5, which comprises an arm 91 clamped by a screw 91 toa lever 96 formed with a stud 92, pivoted to the machine frame 11 adjacent the canend magazine, the stud 92 being secured to a lever 86 connected by means of a rod 87 with another lever 88 pivoted at 88 to the frame 11. Lever 88 carries an adjustable contact stud 89 in the path of a contact block 90 attached to the feed bar 18, so that in the rearward movement of the feed bar the contact stud 89 is engaged, rocking levers 88 and 86 correspondingly. .T he arm 91 has a fastening device 92 operating in a slot 93 for adjustably securing it to the lever 96. The outer end of the arm 91 is formed with a slot 94 for engaging a pin 95 .carried by the stop bar 82, and one end of the lever 96 is formed with an inclined contact face 96 normally disposed in the path of a can end moved by the feed bar 18. With this construction, it is obvious that the forward feeding movement of the feed bar 18 moves a can end 15 in engagement with the contact surface 96 of the lever 91, causing a corresponding movement of the stop bar 82 to position the recesses 84 thereof in a position to receive the projection of the contact block 83 of the die operating slide 65, and upon the rearward movement of the feed bar 18 the contact stud 89 is engaged by the block rocking the levers 88, 86, 96 and 91 in the reverse direction and moving the stop bar 82 to the stop position. If nocan end is moved by the feed bar18 in its next forward movement, the lever 96' will not be engaged, and the stop bar 82 will-not'be moved from its stop position, which insures that a can end must be in proper position at the lining station before the lining die is fully actuated to apply a lining.

In the mounting thecompound receptacle 63 so it can be removed from its operating position, as shown in Fig. 4, without disturbing any of the die operating mechanism, a vertical pivoting rod 97 (see also Figs. 5 and 8) is mounted at its ends in bearing brackets 98 and formed as a part ofone of the guides 66 secured to the upright frame part 67. The receptacle is provided with a corner extension 99 having a vertical bore 100 to snugly fit the rod 97 with a slot 101 in the outer edge of the bore, as shown more clearly in Fig. 5, less in width than the diameter of the bore 100. The lower portion of the rod 97 is formed with two diametrically opposite flattened por tions 102 of a length and diameterto receive the slot 101 of the receptacle 63 when it is in lowered position on the rod, and when it is rotated to register the slot 101 with the flattened portion 102, the receptacle 63 may be bodily removed from or attached to the rod 97 In attaching the receptacle to the pivoting rod,.the slot 101 is passed over the flattened portion 102 and the receptacle is raised above the flattened portion 102, so that the bore 100 is rotatably engaged by the circular bore portion ofthe rod 97, and the receptacle 63 is rotated to engage a lug 103 on its opposite lower corner with a projection 104 on the opposite guide 66. To hold the receptacle in this position, a latch 105 (see Figs. 5, 6, 8 and 9) is pivoted in a bracket 106 on the frame 67 and has an enlarged head 107 adapted to engage in a slot 108 of a lug 109 projecting from the side of the receptacle 63. The latch is. simply raised to disengage it from the lug 109, the enlarged head holding the lug against outward movement when the latch is in engaging position. )Vith this construction the receptacle 63 .can be applied or removed without afliectingthe operating mechanism for the lining die 60. A substantial mounting is afforded to support an extension 110 of the receptacle 63in which a bottle 111 for replenishing the receptacle is held in inverted position (see also Figs. 1 and 2) which operates upon the water bottle princi-" ple to maintain a certain level of the lining compound 64 in the receptacle 63.

After a can end has been supplied with lining compound by the die 60, it is rotated by the carrier drum 40 in a step by step movement until the can end is inverted and brought to a position at the top of the drum. From this position the can end is disengaged upon a further movement of the drum by means of a blade 112, which extends "into slots 113 formed in the adjacent angular edge between two can end supporting faces, so that the blade engages below a can end as the drum is rotated, lifting the can end from engagement with the face of the drum to which it is held by the magnetic core piece. At the far side of each face of the drum, are blocks'114 which in. their uppermost positions engage the adjacent edge of a can end as it is raised by the stripper blade 112, and as the drum continues to rotate in its step by step movement, the blocks 114 push the can end along the blade and deposits it in the conveyor 13 (see Figs. 1 and 2) under a baffle plate 115 where it is engaged by the conveyor chain 14.

A step by step movement is given to the carrier drum by a Geneva mechanism illustrated more clearly in Figs. 3 and 4. A Geneva ice wheel 116 is secured to, the shaft 41,which carries the magnetic drum by fastening screws 117 and has radial slots 118 correspondingin number to the poles and can end engaging faces of the carrier drum 40. A roller 119 projecting from the face of a disc 120 rotatable upon a stud 121 supported by the gear housing 81 forms a pinion for engaging in the slots 118 of the Geneva gear. This disc 120 is rotated by a spur gear 122 secured thereto and meshing with a corresponding gear 123 secured to the shaft 78, so

that the continuous rotation of shaft 78 causes a continuous rotary movement of the roller 119 about the shaft 121, the roller engaging successive slots 118 for moving the Geneva wheel 116 in a well-known step by step manner.

In order to lock the Genevawheel 116and consequently the carrier drum '40 in any one of its several positions for receiving can ends and holding them at the liningstation, the Geneva wheel is provided intermediate the radial slots 118 with locking notches 124 adapted to be engaged by a spring pressed block 125 movable in, a housing 126 attached to the inside of gear housing 81 and pressed in engaging position by a spring 127. To move the block into and out of engagement a lever 128 ismounted at one end upon a pivoting stud. 129 attached to the gear housing 81 and has an extremity 130 extending through a slot 131 in the side of the housing 126 into engagement with a notch 132 in the side of the block 125. This lever is operated by a contact roller 133 adapted to engage the cam face 134 of the disc 120 which carries block 125- in timed relation to gage the Geneva wheel.

the roller 119 for operating the Geneva wheel,

the spring 127 pressing the lever 128 and its roller 133 toward the cam surface 134, which thereupon operates the lever and the locking properly ened upon and secured by a key 137 to the driving shaft 30.

The gear 135 also extends parallel to a flange 138 extending from a sleevs 139 loosely mounted on the shaft 30 and. having a driving gear or sprocket 140 secured thereto for the driving engagement of a chain 141, as shown in Fig. 2. The-flange I 138 is formed with a hole 143 adapted to engage a locking pin 144 carried by the gear 135 and moved therefrom into engagement with the hole in the flange for driving the 1 gear 135 with the power operated sleeve 139.

To operate the pin 144, there is a collar 145 slidable on sleeve 136 and having a projection 146 which is secured to and supports the pin 144 in a hole 147 of the gear 135 which registers with the hole 143 in the flange 138. A spring 148 is interposed between the collar 145 and the sleeve 136 tending to press the pin 144 into engagement with the hole 143.

To control the operation of the engaging pin 144 a hand lever150 is fixed to a'rock shaft 151 and'carries an extending lug 152 (see also Fig. 1) in which is a lock pin 153 pressed by means of a spring 154 into engagement with a pocket 155 or a pocket 156 in the outer face of the frame 23 adjacent thereto. The lock pin 153 has a cross pin 157 to provide a hand hold for withdrawing the pin from its engagement with either one of the pockets 155 or 156, and for rotating the hand lever 150 and the shaft 151 accordingly. At the opposite end of the shaft 151 is a block 158 carrying a boss 159 which forms a housing for a fixed pin 160 and a sliding pin 161 pressed normally outward by spring 162 but limited in its outward movement by a shoulder 163.

To control the operation of the collar 145, two flanges 164 and 165 are formed on the outside of the collar providing a channel for engaging the spring pressed pin 163, v the inner flange having a cam portion 166 for engaging the fixed pin 160 when it is moved toward the collar'145. V

In the operating position of the hand lever 150 the shaft- 151 is rotated to withdraw both of the locking pins 160 and 161 from en'- gagement with the collar 145 so that it will move the pin 144'in position to lock the gear 135 and the flange 138 for rotation together. When the hand lever 150 and the shaft is rotated into the other position, the pin 160 will engage the cam surface 166 of the collar 145, moving the collar along the sleeve 13 6 against the pressure of spring 148. Before the pin engages the cam surface 166 the spring pressed pin 163"will engage the outer surface of the flange 164-and will not move downwardly into the groove between the flanges 164 and 165 until the collar has been ;moved laterally to register the pin 163 with the groove. The pin 163 will then hold the collar 145 and the pin 144 out of engaging position until the hand lever 150 is again operated.

The hand lever 150 thus controls the op eration, of the entire machine, which is entirely automatic, requiring only the filling of the magazine with can ends anda supply of lining compound. The can ends are fed automatically with the flanges turned down and delivered with the lining applied at a different elevation and in inverted position, so that the flangesare turned up and the can .ends discharged into a transverse conveyor.

The operation of the mechanisml'is intermittent, the can end carrier drum moving,to ward, not away from, the can end magazine in inverting the lined can ends.

It is thought that this invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent thatmany'changes may be made in the form, construction and arrange ment of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
